Why You'll Love These Cupcakes
- Both chocolate and peanut butter is tasted in every bite.
- They have a rich chocolate flavor.

My dark chocolate cupcakes are my inspiration for this recipe. They're perfectly chocolatey and pairs so well with the sweet frosting.
Ingredients Needed
Here are some notes on the ingredients we'll be using. For the full ingredients list, look at the recipe card below.
- Flour: I used all purpose flour.
- Cocoa Powder: I used dark chocolate cocoa powder but you could also use unsweetened cocoa powder (like Hershey's).
- Milk: I used 2%, but you can also use whole milk or your preferred milk alternative.
- Oil: Use either canola or vegetable oil.
- Peanut Butter: Use creamy peanut butter.
- Heavy Whipping Cream: I like to add a little to the frosting to help with the creaminess. You could also use heavy cream.
Instructions
Here are the step by step instructions on how to make these rich chocolate cupcakes with peanut butter frosting.
Step 1: Dry ingredients. In a medium bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt. Set aside.
Step 2: Wet ingredients. In a large bowl, whisk together the egg, milk, warm water, oil, and vanilla extract.
Step 3: Combine the ingredients. Add the flour mixture into the wet ingredients and whisk until combined.
Step 4: Bake. Fill the cupcake liners ½ way full (about 2 tablespoons) and bake for 15-18 minutes. Let the cupcakes cool for 10 minutes in the pan before transferring them over to a wire rack.
Step 5: Make the frosting. In the bowl of a stand mixer using the paddle attachment, beat the softened butter, peanut butter, and vanilla extract on high speed until creamy. Add the powdered sugar, heavy whipping cream, and salt on low speed and mix until combined.
Increase the speed to high and beat for another 1-2 minutes.
Step 6: Decorate. Use a piping bag and your favorite frosting tip to frost the top of the cupcakes.
Then drizzle on chocolate syrup.

Expert Baking Tips
- Cupcake Pan: Prep two 12-count muffin pans with cupcake liners. This recipe makes 14 cupcakes.
- Measuring Flour: To help ensure you don’t add extra flour, follow these three simple steps: 1) Fluff up the flour using a fork. 2) Spoon the flour into your measuring cup. 3) Scrape a knife across the top of the measuring cup to level out the flour.
- Combining Ingredients: Be careful not to overmix the batter. Whisk just until the flour is combined.
- Cupcake Batter: Evenly divide the batter amongst the cupcake liners, only filling them ½ way full (about 2 tablespoons). If you fill them any more than that the cupcakes will have large muffin tops and will risk sinking once cooled.
Recipe FAQs
You could certainly use a storebought chocolate cake mix, but I highly recommend you make them from scratch. They're super easy and tastes so much better!
Yes! That consistency of the batter is key to super moist cupcakes.
I have not tried it before in frosting, so I'm not sure how it will turn out. I recommend using either Jif or Skippy peanut butter.

Best peanut butter icing I've ever tasted! And the chocolate cake...don't get me started. So moist and such a yummy chocolate flavor!
I absolutely love that combo!! So glad you did too!
Your Reese’s peanut butter and chocolate cake is the best dessert and I cannot wait to make these cupcakes for my husband and I’s anniversary! They are like minis of the big cake, perfect for two! It’s my husband’s favorite dessert. The peanut butter frosting is to die for. Highly recommend.
I'm glad it's your favorite!
Where I used to live there was a cupcake shop that had peanut butter icing. I've never seen it anywhere else and I love it as it isn't as sweet as other icing. When I saw this recipe I was so happy. I immediately tried it and absolutely love the cupcakes and the icing. Brought a batch into work and my coworkers were raving about the cupcakes, especially the peanut butter icing, doesn't seem to be thing where I'm living now, at least not yet 🙂 The recipe was super easy to follow, the cupcakes turned out perfectly and I even learned how to pipe icing. I've made these a few times now and they are always a big hit.
I love your backstory on the peanut butter icing, Heidi. Thanks for sharing and I'm glad you enjoyed the recipe!
Ahh, chocolate!:)) I don't know what "leftovers" means haha! Never happens at my house!
I know, right?! 🙂
OMG these cupcakes are absolutely drool worthy! What better combo is there than peanut butter and chocolate?
My husband is a true peanut butter fan. We sometimes have 5 jars of peanut butter in the pantry. He would love these peanut butter cupcakes. (I would too)
